I have unfortunately not yet developed any mouse/keyboard app for this. I only use it for https://github.com/tejado/Authorizer

Thanks so much for that, I ended up making my own app using Android USB Gadget and some code I stole from Authorizer.

It's my first app, and it definitely shows, but it works. Though, it's definitely missing a fair number of keys.
